Super-conducting copper

The production of copper that is capable of transmitting 13 per cent more current than present conductors was announced by Dr. W. P. Davey of the Research Laboratory of the General Electric Company at the December 31st meeting of the American Association for the Advancement of Science. These results were obtained with large single crystals of copper, the experimental production of which was recently accomplished in the Schenectady laboratory. Use of single-crystal copper is at present not commercially possible because of the delicacy of the crystals and because of the difficulties of manufacture, but from a scientific standpoint the results of these investigations are of great interest.
